THEODORE LINKE, OF NEW YORK, N. Y.

SANITARY CESSPOOL AND TRAP.

SPECIFICATION forming part of Letters Patent No. 600,732, 'dated March 15, 1898. Application filed December 22, 1896. Serial No. 616,611. (No model.)

T 00% whom it may concern- Be it known that I, THEODORE LINKE, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Sanitary Cesspools and Traps, of which the following is a specification.

The invention relates to a combined sanitary cesspool and trap, and comprises the features of arrangement and construction hereinafter described, the whole being embodied in the form of a new article of manufacture and in but few pieces, which may be quickly and readily assembled.

The sanitary cesspool and trap constructed in accordance with my invention is complete in itself and is efflcient and ready to be applied to practical use with the least amount of labor, delay, and expense.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which Figure 1 is a central vertical longitudinal section through a cesspool and trap constructed in accordance with and embodying the in-' vention, the section being on the dotted line 1 1 of Fig. 2. Fig. 2 is a transverse section of same on the dotted line 2 2 of Fig. 1, and Fig. 3 is a detached central vertical section of a portion of a modified form of cesspool.

In the drawings, A designates the cesspool, which will be of suitable outline and size and is in the form of a receptacle having at its top the central opening B, surrounded by the flange 0, adapted to receive the flange D of the upper section E of the central trap or casing, (lettered F.) The casing F comprises the upper and lower sections, (lettered E G,) which are flanged, as at a b, and secured together by means of the bolts 01. The casing F .is suspended centrally within the cesspool A by means of the flange D, which may be secured to the flange O of the cesspool by means of the bolts e, and centrally over said casing F will preferably be arranged the usual grating H, through which water will pass to the chamber formed within said casing F and thence into the cesspool A. The upper section E of the casing F is provided with the contracted neck I, above which is formed the basin J and below which is formed the concave seat K for the ball-valve L, the latter being preferably of thin metal covered with rubber or other soft material, asindicated in Fig. 1. The casing F is globular in general outline and has at its lower end the outlet-opening M and valveseat N. The valve-seats K N of the casing F correspond with one another and each is adapted to receive the ball L, as necessity may arise, as indicated by the dotted lines showing the extreme upper and lower positions of said ball L in Fig. l. The ball L will be light in weight and adapted to float upon the water,- and when the cesspool contains a normal amount of water, as shown in Fig. l, the ball L will simply ride upon the same Within the casing F and perform no function. When, however, the water in the cesspool A from evaporation orother cause falls below the casing F, the ball L Will contact with the annular valve-seat N and close the opening M at the lower end of said casing F, in which position the ball will operate as a valve to close the outlet from the cesspool to the open air and prevent the escape upward of any gases or odors whichmight under other circumstances ascend fromwithin the cesspool or receptacle A.

The ball L is of great importance also in all instances in which the water may back up through the pipes into the cesspool A, since under such circumstances the water passing upward through the opening M into the casing F would carry the ball L against the seat K and prevent the water from overflowing the cesspool. It will thus be observed that the ball L, while not interfering with the ingress of water to the cesspool, is capable of preventing the escape of gas upward from the cesspool when the water therein is below the casing F and is especially adapted to prevent the overflow of said receptacle A due to the backing up of the water within the outlet from said receptacle.

The outlet from the receptacle A will be in any of the usual desirable forms, two of which are illustrated in the drawings, and the one of which (shown in Fig. 1) is in the form of a siphon O, in the short arm P of which the water Within the cesspool will form a seal which will in a. well-known manner prevent the return of the gases through the outletpipe. The water flowing into the cesspoolA may rise through the short arm P and readily find its exit, as indicated by the arrows in Fig. 1, while that body of water within the short arm P will effectually prevent the entrance to the cesspool of return gases through the exit-pipes.

In Fig. 3 the outlet-pipe from the cesspool is at the upper end of the latter and lettered Q, while the seal is formed within the branch R, extending downward into the cesspool and connecting with said pipe Q, as shown in Fig. 3. Ithus illustrate two forms of escape-pipes from the cesspool and do not limit the invention to these two forms, since various other forms of exit-pipes from the cesspool are well known and any of them may be employed.

Itis unnecessary in the present case to rely upon the seal formed by the water adjacent to the exit-pipe from the cesspool, since the lower end of the casing F is substantially below the water-line in the cesspool and it forms a trap which is entirely efficient, while the water remains above the opening M at the lower end of said casing. When the water falls below the opening M of said casing, the ball L will close said'opening to prevent the upward escape of the gases, as above described. Hence it will be apparent that the present invention does not depend entirely upon the use of a seal connected with the outlet-pipe from the cesspool. If under any circumstances it should be found that the form of seal and outlet from the cesspool A (shown in Fig. 1) have a tendency to siphon the water from the cesspool, this result may in a well-known manner be prevented by venting the upper end of the pipe 0.

WVhen the surface of the ball L is covered with a coating of rubber or other soft material, the valve-seats K N may be left uncovcred; but should it be preferred the valveseats K N may be covered with a thin layer of rubber or other soft material for the purpose of enabling the ball L, either covered or uncovered, to more closely engage said seats K N, this beingafeature of construction and arrangement within the skill of the manufacturer.

The operation of the combined cesspool and trap will be readily understood from the foregoing description, taken in connection with the accompanying drawings, and hence but a further Word of explanation is necessary. The water will pass through the grating H into the casing F, and thence through the opening M at the lower end of the latter into the cesspool A, whence it will pass to the outlet-pipe from the said cesspool and be carried off in any of the usual Ways. The construction is such that the water-line within the cesspool is above the lower end of the casing F, and hence the water ordinarily remaining within the cesspool or receptacle A will seal the casing F and prevent the escape of gases upward through the grating H. When the water is in its normal state Within the cesspool A, the ball L will float upon thesame and perform no function; but when the water within the cesspool by reason of evaporation or other cause falls below the opening M at the lower end of the casing F the ball L will automatically seal said opening for the purpose of preventing the escape of gases upward through the casing F, and when, due to any cause, the water backs into the casing A from the outlet-pipes and rises within the casing F the ballL will be seated at the upper end of said casing F and close the outlet from the cesspool or receptacle A, thus preventing the damages which constantly result from the overflows in cellars and other places.

While I do not limit the invention to the grating H, the same is useful in many places to prevent sticks and other matter from entering the cesspool.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combined cesspool and trap, comprising the cesspool-receptacle A having the outlet for water and at said outlet provided with the trap, said receptacle also having the inletopening B, in combination with the interior globular casing F composed of the flanged and connected sectionsE, G, adapted to be inserted downward through said opening B, and the float-valve L within said casing, the said section E being formed integral with the contracted neck I, valve-seat K, basin J and flange D, the latter being the means for suspending said casing F within the upper part of said receptacle A, and the said section G having the outlet-opening M and valve-seat N; substantially as set forth.

Signed at New York, in the county of New York and State of New York, this 19th day of December, A. D. 1896.

THEODORE LINKE.
